FILTER.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application` filed Tune 14,1904. Serial No. 212.463. I

.To all whom t may concern:

Be it known that I, ARTHUR E. KRAusE, a citizen of the United States, residing at Jer- .sey City, in the county of Hudson and State of New Jersey, have invented an Improvement in Filters, of Whichthe following is a for cleansing the parts, for removing the mud Isectional plan of the same.

and scum collected in the shell, and for admitting air under either the filtration or discharge of the accumulation of foreign matter. l

Support-arms preferably in the form of perforated pipes are fixed in and extend across within the shell and connect with pipes of the aforesaid connections. Upon these ysupport-arms are disks surfaced with suitable filtering material and with oppositely-placed washers surrounding the su port-arms and` at right anglesthereto, together forming filter units between which on the support-arms are spacing-rings, and I rovide means for forcing -together the said) rings, disks, washers, and filtering material to establish liquid-tight joints.

In the drawings, Figure 1 is a sectional elevation of my improved filter, showing the parts broken away transversely. Fig. 24 is a calsection through the erforated supportarms, the disks, vand t e parts assoclated therewith; and Fig. 4 is a section on the line :D Fig. 3, showing the filtering material in part removed.

Iemploy a filter-shell preferably comprising a main body portion a, having a hollow or receptacle base a and a capor cover a2, connected together in any desired manner.'

b` b represent support-arms in the form `of pipes, with perforat1ons12, which are secured pressure for accelerating Fig. 3 is a verti-v preferably one directly above the other, the opposite ends of the said pipe-arms being sto ped by means of plugs 4.

lpemploy one or more disks, preferably of metal and provided with irregular surfaces, which, as seen in Fig. 3, may be in the form of wavy corrugations, as indicated at c, or as,

to one end 3 in the body a of the filter-shell,

angular corrugations, as indicated at c', or

these disks may conveniently be formed of interwoven wires of any desired mesh, as indicated at c2. The disks c c c2 are provided with openings adapted to receive the perforated pipe-arms?) b', and surrounding the ai ipe-arms and at either side of every 1s washers may be covered with any suitable filtering material e-such, for instance, as twilled cotton. The ltering material is secured together at the edges of the disks and employ washers d. The disks -and 4 passes exteriorly over the washers d. I also employ spacing-rings f, which are ap roXimately the same diameter as the was ers d and are placed between each of the disks and its covering of filtering material, so that the vfiltering material covering the said Washers comes between the same and thefsides of the spacing-ringsf. I also employ nuts 5, ada ted to screw on the inner ends of the pe orated pipe-arms to force the washers and the spacing-rings, with the intervening portions ,of the disks and filtering material, together to make a liquid-tight joint between the washers and rings and intervening portions of the iilteringmaterial. It will be readily apparent that with this construction the corrugations of the disks between each pair of washers d provide passages for the filtrate on either side of each of said disks, whereby the material to be filtered by passing through the filtering material readily reaches the interior of the pipe-arms b b', which are preferably slightly smaller .than the interior of the washprovided lwith a valve 1 1.

IOO

13 is a pipe connected to the T-coupling 9 and provided With a valve 12, and 14 is a pi e leading from the base of thefilter-shell and filted with a valve 15, and I also employ an airpipe 16, leading to the upper part of the filtershell and provided with a valve 17, and I may also find it convenient to shell with one or more han -holes 18. In the top of the shell I provide an air-cock 20.

In the operation of the apparatus the material to be filtered is conveyed to the interior of the shell by the pipe 6 and fills the same up to the air-cock 20. This valve is then closed, and the liquid then passes through the filtering material and by the Way of the channels in the corrugated disks and the spaces between the disks and Washers to the interior of the pi e-arms b b andis thence led away by the pipe 13, it being understood that during this operation the valves 11, 15, and 17 are closed.

For cleansing urposes-the valves 7, 17, and 12 are closedp and the valves 11 and 15 openedv in order that steam, water, or other agent forfc'leansing the filtering material may be passed through the filter in the opposite direction. The air-pipe 16 is provided to carry on the filtering process or cleansing under pressure, as is often found expedient, the air being admitted to the interior of the filter-shell by this pipe.

It is to be understood that in cases Where the material to be filtered is of such a composition as not to require-a considerable space between the filter units I may dispense With the spacing-rings, and also the same effectl as is obtained by using the spacing-rings may be obtained by making the Washers of sufficient thickness.
